Blood Group O-ve

O negative blood group

Review question time!

Q.Which is the universal donor?
And why?

A:- O negative. No antigens.

But it still has anti-A and and anti-B antibody...

Won't they react to the RBC present in the recipient?

Confused at the O negative thing. I Will explain it here.

The things is when you give blood to the recipient.

The plasma in the O- blood is rapidly mixed with the 5 litres 

of the recipients plasma.

So the antibodies are diluted. They are not effective in causing 

agglutination of the recipients RBC.

Why doesn't this happen with any other mis matched blood groups?

Cause in those cases the RBC's are having antigens.

So they are rapidly agglutinated.

Mismatched blood transfusions are due to agglutination of donors RBC, 

never the recipients RBC.

I HOPE THIS WAS HELPFUL...

Thanks
